Yes.
And if he's like the leader on a gig I did a couple months back he'll tell you to learn all of them. As if there was a chance in ____ you'd actually play all of them
I had a leader send me a list (song titles, no audio or sheet music of any kind) of about 30 songs a couple of days before a last minute gig, wanting to know which of them I knew. I knew all but five and I let him know that. He told me he wanted to do all of them.
We ended up doing about ten songs for the two set show... and it went very well.
Ah, show business.
